Water treatment chemicals are a diverse group of substances designed to enhance the quality of water. They are used in various processes, including coagulation, flocculation, disinfection, and corrosion control. Commonly supplied chemicals include chlorine, alum, polymer, and sodium hypochlorite, each fulfilling specific functions in the treatment process. The selection of appropriate chemicals depends on various factors, including the type of contaminants present in the water, regulatory standards, and the intended use of the treated water.
Biological APIs, or biopharmaceuticals, are derived from living organisms, including humans, animals, or microorganisms. These APIs are produced using biotechnological methods, such as recombinant DNA technology, and are often more complex than synthetic APIs. Examples include monoclonal antibodies, insulin, and vaccines. Biological APIs have transformed therapeutic approaches, particularly in treating chronic and complex diseases like cancer and autoimmune disorders. However, they generally require more rigorous regulatory oversight due to their complex nature and immunogenic potential.
